My Fire has never been out of the Marware case since I got it but today it slipped out of my hand and landed face down with the cover open.
The snap was loud and when I picked it up saw the gorilla glass had shattered. It still starts and I can still use it but the shards of glass are a problem.
I called Kindle support and they said they would replace it for $100 exchange.
I looked online and found a replacement screen here for $34.99.
Kindle Fire Glass and Digitizer Assembly
Fortunately, I have the Square Trade Warranty and contacted them and will have a replacement here by Wednesday.
Gonna be a long weekend.
